CustomSiddur Orthodox siddurim follow the style and translations of the original Hertz Authorized siddur. Since the original Hertz text is in the public domain, CustomSiddur has modernized the language in ways similar to other popular Orthodox siddurim.

Your siddur is designed just for you. Only the prayers that are appropriate for your special day are included, and we can add space anywhere you like. We can include your own readings, designs, and anything you want to write. We put the Torah/Haftarah portions right in the Torah service, so nobody will be juggling books or searching for the right pages.
